UNIVERSAL HAUL-AND-DRAW COUPLER (HDC)
The lift-type HDC comprises a clevis as
well as (optionally) drawbar and “Py-
thon”-type facility.
Clevis ( ТСУ - 3В)
The coupler is intended for operation
with single-axle and tandem-axle trailers.
It consists of a traction clevis (1) with a
coupling pin, and a body (2). The traction
clevis body is connected with the bracket
(4) by means of the pin (3). The traction
clevis position can be changed as to
height by moving it over the guides in the
bracket (4) and fixed by means of the pin
(3).
Pull-Bar Mechanism (tow bar HDC- 1М -
01)
It is intended for coupling the tractor with
heavy trailed and semi-trailed machines.
It consists of a bearing support (5) and
drawbar (6) connected with the support
by means of the axle (7).
The draw-bar (6) is adjustable to dimen-
sions of 400 and 500 mm between the
PTO end-face and the point of attach-
ment of the shackle of the trailer by rein-
sertion of the axle (7) into holes in the
draw-bar (6).
“Python” Type Arrangement (ТСУ - 2Р)
It is used to operate the tractor with
semi-mounted agricultural machines and
single-axle trailers. The arrangement
(pos. 8) is installed in the guides of the
bracket (4) and fastened by bolts (9). To
attach a trailer, it is necessary to pull out
the pin (10), put the trailer’s coupling
shackle on the thrust journal (8) and refit
the coupling pin to guard against sponta-
neous disconnection of the trailer’s
shackle.
IMPORTANT! The "Python" arrange-
ment can be only used after the draw-
bar (6) has been dismantled.
